The part I remember best is sitting on a stage next to Tony Blair, who is going to introduce John Prescott (Note for non UKans: Tony Blair, former Prime Minister of the UK, and John Prescott, former Deputy Prime Minister, and a man prone to gaffes and verbal fuffle) who will be giving a speech.
So someone introduces Tony Blair, who goes on to introduce John Prescott. Prescott comes to the podium, talks for a bit about Blair, and then introduces Blair again to give a speech. Blair, puzzled, goes back, says a few more words, and says that Prescott will give a speech.
You guessed it: Prescott introduces Blair again who shrugs and gives a strange little speech. I left the stage at this point and went to the furthest part of the venue, way up in the rafters, to retrieve my luggage.
